Doubled up on accident

Okay so, I usually take my birth control pill at 8:30 every morning. And today, I did just that. However, tonight, I turned on my phone screen (my alarm clock is right next to the date) and I mistakenly looked at the alarm thinking it was the date and that I forgot and was late taking it. So I took another pill not realizing until after that I doubled up.

(I took Saturday and Sunday pill today)

Should I take the Monday's pill as usual tomorrow, or skip tomorrow and take it the day after?

And am I still protected or do I need to use back up methods?
